Answer:
What percent of the school are girls? 55%
What percent of the school are boys? 45%
How many boys are there? 162
How many girls are there? 198
Step-by-step explanation:
The number of girls = 198
The percent of girls = 198/360 x 100% = 55%
The number of boys = 360-198 = 162.
The percent of boys = 162/360 x 100% = 45%.
(x - 2)/5 = 3
Multiply 5 to both sides:
x - 2 = 15
Add 2 to both sides:
x = 17
The formula for area of a triangle is A= bh/2
So 8•5/2 is 40/2= 20
Then 13•19/2 is 247/2= 123.5
Answer:
Volume of a parallelogram is v=whl
Area of s parallelogram is A= bh
Circumference of a circle= rd
Area of a circle= rd^2
Area of a triangle is 1/a <em>bh</em>
Area of a trapezoid is 1/2(b1 + b2)h
Perimeter of a quadrilateral is 2L + 2W
